IMPROVEMENT IN NUT-LOCKING WASHER.

The Schedule referred to in these Letters Patent and making part of thesame.

nop-.

To all whom it may concern Be it known that I, WILLIAM H. WILLIAMS, ofCanton, in the county of Stark, and State of Ohio,

have invented certain new and useful Improvements in Nut-LockingWashers; and I do hereby declare that the following is a full, clear,and exact description of my invention, reference being had to theaccompanying drawings, forming a part of this specilication, and to theletters of reference marked-thereon, of which drawings- Figure 1 is anelevation, showing au application of my invention.

Figure 2 is an end view of the same.

Figure 3 is a longitudinal section of the same.

Figure 4 is an elevation "of nut-plate.

Figures 5 are detail views of washer.

Figure 6 is a perspective view, showing theapplication of my invention,with the nut looked.

The nature of my invention consists in the construction of a malleablemetallic washer, provided with one or more arms or projections on itsinner face and around the bolt-hole, which arms or projections tit intosuitable slots or indentations in the bolt-hole in the nut-plate, andthus prevent the washer fi'om turning around the bolt, the nut beingsecured by said washer from turning, by bending the edges of said washerover the side faces of the nut, whereby I obtain a simple, cheap, andeffectual device for preventing nuts from working loose, from jarring,or other` causes. A

To enable others skilled in the ait to make and use my invention, I willproceed to describe its construction and operation. Y

The washer E is punched out of wrought-iron, brass, or any suitablemalleable metal, and is conveniently made of the form shown in figs. 5,in which the lei-'thand figure showsthe blank washer as l:h'rst punchedfrom the sheet-metal, and the centre and right-hand figures showthewasher after the arms a a have been turned up at right angles withthe face of the washer. Y

The nut-plate G, or plate against which the nut or washer has a bearing,has the slots j' f cut at the sides of the bolt-hole, as shown iu Iig.4; which holes are of a suitable size to admit the arms a a, which t inthem, as shown in lig. 3.

In the. application of this device, herein shown, A represents the webof a railroad-rail, and B C, the sh plates, which are to be secured toit'.

The bolt F is passed through 'the hole in 'the parts B and C, and thewasher E (its over the end, the arms a a fitting in the slots ff of thenut-plate, as shown.

The nut D is then turned on the boltF until brought up tightly againstthe washer E, when it is prevented from turning oli, by 'bending theVedge of the washer over the side face of the nut, as shown in iig. 6.

It is evident, that with the arrangement shown in iig. 6, the nut Dcannot turn, unless the washerE also turns, and that said washer cannotturn as long as the nut D remains screwed up against it, thus securingthe arms a a in the slots ff, in the'plate C.

Instead of the bent arms a ,depressious could be formed in the washer E,and around the hole b, which 'should iit in corresponding indentationsformed aroundv the bolt-hole in the nut-plate C, in a manner readilyseen, tlms preventing th-rwasher from turning, wheu pressed intoplace bythe nut.

'lhe peculiar utility resulting from this construction is, first, thatthe arms or depressions in the washer, and the slots or indentations inthe. nut-plate, can he iliade at the same time, and bythe same operationthat cuts the washer or punches the hole in the nutplate, so that theapplication of the invention costs but a trifle; and the secondadvantage being, that the position o t' the washer-arms, under thecnt'repart of the nut, allows of the use ot' very short arms on the washer, asthere is no chance for said arms to get out ofthe slots inthe nut-plateuntil the nut is turned off;

Having thus fully described my invention, I- do not claim as'new theprinciple of seouringthe nut and washer together, by turning the edgeofthe washer over a side/face ot' the nut; nor do l claim the use ofarms on a'. washer, in connection with slots or indentations in thenut-plate, for the purpose of preventing the washer from turning, whensaid washer is constructed of inflexible material, or is united to thenut, to be held by other and difereutmeans from that herein described;`but \Vha't I do claim herein as new, and desire to secure by LettersPatent, is

The nut-locking washer herein described, the same being constructed ofmalleable metal, with 1arms or depressions a a, arranged around thebolt-hole b, and

fitting into slots or indent-ations ff, in the nut-plate, and beingcaused to look the nut by the turning of'it's. edge over a side tace ofthe nut, substantially in the,

manner and for the purpose herein specied.

As evidence that l claim the foregoingwitness 'my hand, this 31st day ofMarch, 186i).
